Title:
HYBRID TRANSPARENT CONDUCTIVE ELECTRODES
Document Type and Number:
WIPO Patent Application WO/2010/062708
Kind Code:
A3
Abstract:
Methods and devices are provided for improved photovoltaic devices. In one embodiment, the transparent electrode of a thin-film solar cell is replaced in part by a sheet of nanowires. One technique for use in present invention comprises forming a solar cell having: a) a thinner than usual transparent top electrode of a conductive material having a reduced thickness and b) an interconnected network of nanowires in contact with and/or coated by the top electrode. In some embodiments, the top electrode and network of nanowires increases overall power output of the solar cell compared to an otherwise identical cell using only a) a top electrode layer of the material at a thickness and light transmission equal to a combined thickness and light transmission of the top electrode and the network of nanowires, or b) an interconnected network of nanowires of thickness equal to the combined thickness and light transmission.
